We found that NSCLC cells with miR-330-3p overexpression showed relatively high expression of vimentin, N-cadherin, Slug, Claudin-1, Snail, Twist and ZEB1 (mesenchymal phenotypic biomarkers), and relatively low expression of E-cadherin (an epithelial phenotypic biomarker). The gene discussed is SNAI2; the disease is non-small cell lung carcinoma.
